What is the diameter of the opening of a stock 1984 GS (carbureted) exhaust manifold? I've searched several threads and can't find that specific info...anybody got that piece pulled and can get a measurement for me?

Thanks in advance to any and all that can help me here...

 

engine or muffler side?

 

On my '83 engine, muffler side is about 2". I know because I just pulled mine not long ago for the header swap, but was going to do a manifold exhaust at first, decided to just get a header. I'm sure it's metric, some wierd *** mm size, but for all general purposes, it's 2".

I'm also sure wackyracer is going to tell me I'm wrong, and will have the exact metric size, but for general purposes, it's 2".

 

nah, thats about right.

 

Thank you, Gentleman! That was exactly what I needed to know! Full steam ahead with my custom exhaust ideas for Tweety...
